となる。However, synthetic resins having excellent heat resistance, such as nylon 6, are expensive and their color tone is limited, so that desired color tone and gloss cannot be selected. For this reason, in the related art in which the support frame 2 is formed of such a synthetic resin, the material cost increases and the price is high, and the color tone and gloss of the support frame 2 are limited. The color tone and gloss are also limited from the balance, and it is difficult to make the rice cooker main body 1 and the lid 11 into desired designs having various colors and gloss.

炊飯器を構成することが可能となる。[Function] When the rice cooker is used, heat from the pot is conducted to the heat-resistant member, but since the heat-resistant member is made of a synthetic resin having excellent heat resistance, the heat-resistant member is sufficiently resistant to the heat and softened. There is no deformation, and heat conduction from the pot to the support frame is suppressed by the heat-resistant member, so that the support frame can be formed of a synthetic resin having low heat resistance. Since synthetic resins with low heat resistance are inexpensive, material costs can be reduced, and in synthetic resins with low heat resistance, the color tone can be selected from a wide range of colors. It is possible to configure a rice cooker of a desired design by selecting various colors and gloss in consideration of the balance with the main body and the lid.

In particular, in the invention described in claim 4, since the operation portion is provided at a position corresponding to the position where the heat-resistant member is disposed,
It is possible to more effectively suppress the heat conduction from the pan to the operation unit, and more reliably suppress the temperature rise of the operation unit.

Since these heat-resistant members 15 are formed of a synthetic resin having excellent heat resistance, they are sufficiently resistant to the heat and are not softened or deformed. The support frame 2 is formed of a synthetic resin having low heat resistance. However, the pot 8 and the inner frame 3 do not directly contact the support frame 2, and therefore, the heat from the pan 8 and the inner frame 3 to the support frame 2. The conduction is suppressed, so that even if the support frame 2 is a synthetic resin having low heat resistance, it can sufficiently withstand.

Therefore, in the rice cooker according to the present invention in which the support frame 2 is formed of such a synthetic resin, it is possible to reduce the material cost and make the rice cooker inexpensive. it can. In the case of a synthetic resin having low heat resistance, the color tone and gloss of the support frame 2 can be selected in a wide variety of ranges, so that the restrictions on the color tone and gloss of the support frame 2 are greatly relaxed. Various colors and gloss can be selected in consideration of the balance between the color and gloss of the rice cooker main body 1 and the lid 11.

b and the outer surface of the cylindrical portion 2a are often touched by the user's hand. However, heat conduction from the pot 8 or the inner frame 3 to the support frame 2 is suppressed by the heat-resistant members 15. Operating portion 2 of the support frame 2
There is no danger even if the user's hand touches the outer surface of the b or the cylindrical portion 2a, and the safety is improved. In particular, one of the heat-resistant members 15.
Since one of them is arranged at a position corresponding to the operation unit 2b, heat conduction from the inner frame 3 and the pan 8 to the operation unit 2b can be more effectively suppressed, and the temperature rise of the operation unit 2b can be more reliably suppressed. .

That is, since the outer radius R1 of the heat-resistant member 15 is formed so as to correspond to the size based on the small-sized support portion 2c, it is needless to say that the heat-resistant member 15 can be attached to the small-sized support portion 2c. That is, attachment to the large-sized support portion 2c is also possible. Since the inner radius R2 of the heat-resistant member 15 is formed so as to correspond to the outer diameter of the inner frame 3 having a large size, the heat-resistant member 15 is attached to the support portion 2c having a large size. In any case, even when attached to the small-sized support portion 2c,
The inner frame 3 having a larger size or the inner frame 3 having a smaller size can be arranged on the inner peripheral side thereof, and thus can be commonly used for rice cookers having different sizes.
